[lxc-users] lxd - autostart unreliable on busy servers

[Tomasz Chmielewski]

When I restart a busy server (running several containers, creating 100% 
IO load for about 10 mins after start), my lxd containers do not 
autostart reliably.

If I start them manually later on, they start fine (although "lxc start 
containername" needs a while to return).


Is there a way to make lxd autostart more reliable? Perhaps it's some 
kind of timeout which needs to be increased somewhere?



In the log, I can see:

not send a reply, the message bus security policy blocked the reply, the 
reply timeout expired, or the network connection was broken.
